or also Agena. With a magnitude of 0.9, it is the 10th brightest star in the sky. Together with the star Toliman, from which it lies only four and a half degrees, it forms a good landmark for identifying the Southern Cross, thus preventing confusion with the so-called False Cross, which is formed by the stars of the Ship's Keel and Sail. Although, unlike Toliman, this blue-white giant is fainter in the sky, it lies about 100 times farther away. Its absolute magnitude is -5.5. So if it were located where Toliman is, it would be about a -10th magnitude star!
